In a medium sauce pan, melt butter. Add flour and mix thoroughly. Cook over medium heat for 3 minutes. Do not brown. Gradually stir hot milk into flour mixture until it forms a smooth sauce. Add bay leaf and cook for just a few minutes. Remove bay leaf and chill.
Squeeze any liquid from the crabmeat and add it to the flour mixture. Add red pepper, onion, breadcrumbs, cayenne, lemon juice, worcestershire sauce, salt and pepper. Mix thoroughly. Cover and chill for 30 minutes or overnight.
Form crab mixture into 2" balls. Roll in breadcrumbs and flatten. In a skillet, heat butter. Add crabcakes and brown on each side.
In a small bowl, combine mayonnaise with the lemon juice, garlic, salt and black pepper. Mix well and set aside.
